Falling detection method, falling detection device and wrist type device

Abstract

The invention discloses a falling detection method, a falling detection device and a wrist type device. The falling detection device disclosed by the embodiment of the invention comprises a triaxial acceleration sensor, a vertical motion speed value and non-rotation state speed value acquisition module, a first judgment module, a second judgment module, a third judgment module, an angle deviation acquisition module and a fourth judgment module. According to the falling detection device disclosed by the invention, the acceleration sensor is adopted for setting different threshold standards according to different people groups, so that falling with different strengths can be detected, serious consequences caused by falling can be avoided, and the falling detection device is simple and convenient to use.

Description

technical field [0001] The invention belongs to the technical field of detection, and in particular relates to a fall detection method, a fall detection device and a wrist device. Background technique [0002] With the development of computer technology, wireless communication technology and medical technology, society has gradually entered the era of electronic health. Entering the 21st century, the reform of the domestic medical and health system is also being incorporated into the electronic health plan. E-health is the all-round application of information technology in the field of health care, and it is the most important revolution of modern medicine and health in health care. With the continuous development and improvement of wired and wireless information network infrastructure and terminal equipment, people can enjoy health services anytime and anywhere in the near future. [0003] According to the recent results of China's research center, the proportion of Chine...

Problems solved by technology

With the increase of age and the decline of human body function, the elderly are often prone to falls, and falls rank among the top ten accidental injuries of the elderly, and if there is no guardian around after the fall, it will often lead to unpredictable results.

[0004] In order to improve the accuracy of detection and the design of algorithms, most fall detection equipment at home and abroad are developed based on parts that are not prone to strong movement changes such as the chest, and wearable fall detection on the wrist is very rare.
